| With the development of mountainous highway construction,disease problems of highway slope is also becoming more and more.For many alternative treatment schemes,it is difficult to accurately decision-making method to control the ideal treatment schemes. So we need to further research all kinds of slope treatment technology,and the contrast analysis, in order to selectively be used in actual engineering, and proposing an optimization method of the slope treatment for improved decision-making, make the slope treatment become more scientific and reasonable.The main contents of this paper are as follows:?To study the influence factors of slope stability;Then introduce highway slope destruction form and disease types,finally is focused on in this paper, the retaining wall in highway slope measures management method application design,and study the mechanism,advantages and disadvantages of the retaining wall,to adapt to the conditions and the status of the application.?Summarized the destruction of mountain highway slope classification,slope type and the factors affecting the stability of slope. The main factors influencing the slope stability including geological condition,landform,hydrology and climate conditions, the external environment and other factors,the influence of these factors on the slope stability is not the same,some plays a main role, some secondary role.?For a variety of retaining wall in the form of carried on the thorough research, as well as the selection of various forms of retaining wall and the corresponding application condition was summarized in detail; all kinds of earth pressure on retaining wall and retaining wall stability calculation, calculation theory.?Slope is divided into the following three categories;the basic disease landslide, collapse,peeling off. Principle, the design steps for optimization design of retaining wall were studied. Are the major factors which influence the stability of slope, the properties of the rock mass,rock structure and structure,hydrogeological conditions,weathering,and climate effect of earthquake action,geomorphic factors. "Integrated design,local materials,in case is given priority to,to ensure safety is the basic principles of slope comprehensive protection design;In line with ecology, characteristics,economic,beautiful design principle,fully respect landform;Roadbed protection shall be in accordance with the principle of design,construction and maintenance of the combination of adjust measures to local conditions. Attaches great importance to the subgrade drainage design,to do a good job of out of surface water and groundwater;Give priority to use plant protection, and try to choose native species; For water, waves, wind,precipitation and other factors may cause of subgrade damage, shall be set protective engineering;Comprehensive protection should follow the guiding principle of practical, economic,beautiful, for the purpose of driving service,in a safe, saving,science and nature for the overall design goal.?Slope design is to solve the fundamental problem in slope stability and choose a reasonable balance between the economy,with the most economical way to make service, every effort should be made to meet the requirements of stability and reliability of slope engineering building.Pay attention to dynamic comprehensive control, selected the best scheme comparison.?With stone county,south bin industrial park slope engineerings,carries on the comprehensive evaluation on the stability of landslide,in practical engineering design of retaining wall is through repeated checking different index finalized the plan,to complete the optimal design of the retaining wall. |
